Sugarcane aphids continue to colonize Johnsongrass in Hill County and grow in number. Three sites were sampled on March 17th and all three were infested with SCA. The presence of large colonies this early in the year, most likely due to a milder winter, could indicate earlier infestations in sorghum.
No winged aphids were found on the 17th (3 sites) or the 25th (2 sites). This may be due to the cold weather and rains.
